JACKET 0R HOODl FOR USE IN CONNECTION WITH THE EXHAUST-HEADS 0FHOT-WATER URNS 0F CDFFEE APPARATUS.

Patented June 26, 1906.`

Application ned July 7,1905. serial No. 268,679.

To all whoml 'it may con/cern.;

1 3e it known that I, ELIE J. MONEUSE, a c1t1zenlof the United States,residing at New York, 1n thecounty of New York and State of New York,have invented certain new and useful Improvements in Jackets or Hoodsfor Use in Connection with the Exhaust-Heads of Hot-Water Urns of CoffeeApparatus, of which the following is a specification.

This invention relates to improvements in .the pressurein the water-urnreaches the Y point where it blows off, thus preventing ac'- cident byscalding and inconvenience in at# tending to the apparatus.

A further object is to so construct the device that the steam when itblows off will be condensed in the head or jacket around theexhaust-headand be drawn olf gradually through a pi e or other suitable means forconducting t e water to a suitable point or outlet or waste. Y

A still further object is to so construct the top of the hood that itwill aiford absolute protection for the air-inlet valve of theexaust-head, and thus render it practically impossible to close saidvalve and prevent they necessary amount of air from passing into thewater-urn when the contents of said urn, or a part thereof, either steamor water, is removed, the air-supply being necessary when theconnectionbetween the water-urn l and colee-urn is openedl v A It sometimeshappens through carelessness'or lack of understanding of the a paratusthat accidents occur .in whichl t `e attendants 4are scalded through theexcessive exhaust of hot water and steam, due to the fact that theexhaust-head exhausts into the open air, and the hood about to bedescribed is designed to prevent this. Further, the

Water-urn is sometimes injured and indeed or openin dental or carelessStoppa e of the air-inlet valve` ofthe exhaust-hea which stoppageprevents the admission of air to the urn to replace the water in saidurn as it is being drawn off, and the peculiar construction of the topof the hood in the present invention is designed to protect theair-valveand render its stoppage practically impossible.

sometimes collapsed by reason of the acci--V With the above objects inview, and others looking to the general improvement of .devices of thischaracter which will become apparent in the course of the followingdescription, I will now proceed to describe the device in detail andpoint out the features of novelty in the appended claims.

In the drawings, Figure 1 shows a side elevation of the water-urn withmy' improved device attached thereto, showing the water connections thatlead to the coiee urn or urns, said urns being omitted,.since they havenothing to do with the present invention. Fig. 2 is a central verticalsection'of the exhaust-head and my improved hood or `jacket surroundingthe same; and Fig. 3 is a erspective view of the removable top of the 0oshowing more clearly the manner, of perforating the same.

Referring to the drawings, the numeral 1 represents the water-urn ofusual construction, and 2the exhaust-pipe connectedwith the steam-spaceof said urn, to the upper end of which pi e is secured the exhaustead 3,having gui ed in the web 4 therein the exhaust-valve 5, which isbeveled, as indicated A yat 6, and normally resting in a corres ondingseat 7 in the upper part of the head). vThis valve has a central opening(indicated by the numeral 8) for the admission of air through saidopenin to the water-urn. Thiso enin 8 is norma y closed by a valve 9,orme with a stem 10, which passes through a screw-plug 11 in the lowerend of the hollow extension 12 of the valve proper, 5, and around thestem of the valve 10 is va light spring, which is interposed between theairvalve head 9 and the screw-pllug- 11 for the obvious purpose ofkeeping t e valve-head 9 normally seated. Through the hollow extension12 ofthe exhaust-valve is an aperture 13, which permits the air when thevalveead 9 is moved from its. seat to ass into the urn.' The screw-plug11 has a ateral ange or ledge 14, between which and the web 4 isinterposed a s ring 14', suitably tensionedv and holding t e exhaustvalve seated under normal conditions. The construction just described,which involves the exhaust-head, is common in apparatus of thischar^cter.

In ada ting my invention to the described exhaustlead I provide ascrew-nut 15, work ing on a thread on pipe 2, and provide a acking-ring16, between which and the ower hexagonal flange 17 of the'eXhaust-headcasting is clamped the inturned flange 18 of the condensing hood orjacket 19'. This hood or acket extends considerably above the ex.-

aust-head, as shown, and is provided near,

its bottom with an outlet-opening 20, internally screw-threaded for thereception of a drip-pipe 2l, through which the water the result of thecondensation of the steam and other water in volurnegpasses to anysuitable point of outlet or waste'.

The hood is provided or, rather, constituted in part, by a removable top22, formed with a depending flange 23, provided, preferably', with twooppositelydisposed rectangular slots 2li, which in conjunction with theshort laterally-extending pins 25, serve to form a bayonet-joint, bywhich means. the top is held rm'ly in place in such a manner as willpermit its easy removal by silightly turning the same whenrit is desiredto have access to the inside of the hood for cleaning or other purposes.Near the outer yperihery of the top l provide a circular series o smallopenings 2G, primarily for the purpose of admitting air to the' hoodwhen necessary and forl the secondary purpose of permitting the escapeof steam should the volume of exhaust reach the point where such outletis necessary. V

Depending from the top on the inside thereof, near the line ofperforations 26, and surrounding the exhaust-valve of the eX- haust-headis a circular continuous flange 27 When water and steam is blown ofit isreceived within this flange, the steam being condensed and the waterdeilected downward around the exhaust-head to the lower part of the'hoodor jacket, from whence it passes through the drip-pipe. The top or coveris preferably formed with a doine 28,which, aside trom bei-ngornamental, has utility, its utility consisting in that it prevents atowel or other article which may be carelessly thrown over the apparatusfrom stopping up the perforations 27 and insures at all times theadmission of air to the air-inlet valve of the eX- haust-head, the greatnumber and diil'erence in location oi" the perforations- 27 also tendingto the accomplishment of this object.

The construction of the hood or jacket is scacco s-uch that it can bereadily attached to the exhaust-head now commonly used upon urns of thischaracter.

When through neglect or otherwise the pressure in the urn exceeds thatdesired or required, the pressure will lift the valve 5 and the waterand steam will be projected with force against the top of the jacket orhood within the space inclosed by the flange 27 and will be deflecteddownward on all sides ol' t-he exhaust-head and will pass out. of thedrip-pipe without danger, injury, or inconvenience to the attendants,and at the same time pro er indications will be given that prompt t eattendants to take further recautions to prevent further blowing oilothe water and steam.
